Fix for bug #40788.
2003-06-05 Jeffrey Stedfast <fejj@ximian.com> Fix for bug #40788. * providers/pop3/camel-pop3-engine.c (camel_pop3_engine_new): Now takes a flags argument. Currently there is only 1 flag which can be used to disable Pop3 server extensions. (get_capabilities): Don't check for Pop3 server extensions if the DISABLE_EXTENSIONS flag is set on the engine. (camel_pop3_engine_iterate): If we get a response that is neither +OK nor -ERR, default to treating it like a -ERR. * providers/pop3/camel-pop3-store.c (connect_to_server): Check for the disable_extensions param. * providers/pop3/camel-pop3-provider.c: Define a checkbox to disable all POP3 extension support. svn path=/trunk/; revision=21438
